SASH-BALANCE.

' SPECIFICATION forming part of Letters Patent No. 375,252, dated December 20, 1887.

Application filed May 25, 1857. Serial No. 239.328. (N0 model.) I

To all whom it may concern:

Beit known that I, J AOOB BASTIAN, of Dansville, in the county of Livingston and State of New York, have invented certain new and useful Improvements in Sash-Holders; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the figures and letters of reference marked thereon.

This invention relates to certain improvements in window-sash holders, and particularly to that class of sash-holders which employs a rack-bar mounted on the sash and a gear or friction wheel engaging therewith mounted in the window-frame, or vice versa, said gear-wheel being retarded in its rotation by suitable devices, in order to prevent the falling of the sash, as will behereinafter more fully described, and pointed out in the claims at the end of this specification.

In the accompanying drawings, Figure l is a perspective view of my invention with the sash and window frame in dotted lines. Fig. 2 is a horizontal section taken through the center of the gear-wheel. Fig. 3 is a view of the gear-wheel, drum, and friction-brake removed from the frame. Fig. 4 is a view of the rear side of the gear-wheels, showing the pawls. Fig. 5 is a modification.

Similar letters of reference in the several figures indicate the same parts.

In the window-framing, preferably on the right-hand side and at about the height of the top of the lower sash, are formed two recesses for the reception of the frames A, carrying the gear-wheels and brake attachments, one for The said drum Gis mounted on an axle, a, which,

when pressed back, takes its hearings in the slots bin the frameA. At one side of the drum the axle is enlarged into a collar, which has a drum.

The rear side of the gear-wheel E, or the side next the drum, is grooved for the reception of small gravitating-pawls c, which drop into the depressions in the wheel G and effectually prevent its rotation in one direction without carrying the drum, although permitting it to rotate freely in the opposite direction. A collar or washer, d, is placed on the axle outside the wheel to prevent its dropping off and the pawls being lost when the device is removed from its frame. The spring B is of such shape that it will normally hold the drum away from the frame A and the axle upon which it is mounted out of its bearings in said frame, but leave them in position to again enter them upon being pushed backward.

' Mounted on the window-sash is a rack-bar, F, preferably set in until its teeth are flush with the surface of the frame, with which rackbar the gear-wheel engages.

The operation of the device will now be readily understood. The end of the spring forming the friction-band for the drum, having been made tight enough by means of the screw-bolt D to just or slightly overbalance the weight of the sash, will, through the medium of the ratchet-wheel, pawls, and gearwheel engaging the rack-bar, hold the sash in any position to which it may be adjusted, at the same time allowing it to be readily and easily moved up or down when slight pressure is applied.

The objectof mounting the drum and ratchetwheel on the spring is to compensate for any looseness between the frame and sash, and, while causing the gear-wheel and rack-bar to engage with sufficient force to render the device operative, will not render the sash hard to move by causing undue friction on the opposite side.

Although it is perfectly obvious that the friction-drum may be made of iron or other suitable material or metal, I preferably make it of box-wood, and secure it to the axle as follows: At the side of the ratchet-wheel G is a flange, f, of nearly the same diameter as the drum itself, having holes or perforations therein. The drum is placed on the axle close up beside this flange, and secured thereto by screws or rivets, as desired, inserted through the said holes. (See Fig. 2.) This flange is recessed into the gear wheel and the pawls are located at approximately the center of the wheel, the thickness of metal outside the pawls being about the same as that of the flange.

If desired, the friction-band surrounding the drum may be made of a separate piece of metal riveted or otherwise secu red to the mainspring. It will also be seen that the walls of the slots in which the axle a takes its bearings may be extended out so as to receive the downward thrust of the sash, the spring in this case being made somewhat lighter.

The slots are preferably somewhat wider than the diameter of the axle, so as to allow a slight up-and-down movement of the same, as will be seen upon reference to Fig. 5.

I do not wish to be limited to the use of a gear-wheel for engaging the sash, as it is plain that a frietion-wheel may be used in its stead.

Having thus described my invention, what I claim as new is 1. In a sash'holder, the combination, with the wheel for engaging the sash and a drum connected thereto by a pawl-and-ratchet connection, of a spring supporting the said wheel and drum and having a friction-band at its upper end for engaging thedrum, substantially as described.

2. In a sash-holder, the combination, with the wheel for engaging the sash and a drum connected thereto by a pawl-and-ratchet c0nncction,of a frame in which they are mounted, having bearings therefor, aspring for holding them normally away from said bearings, and a friction band or brake applied to said drum, substantially as described.

3. In a sash-holder, the combination, with the wheel for engaging the window-sash, a drum connected thereto bya pawl-and-ratchet connection, a frame having bearings therefor, and a spring for holding them normally away from said bearings, of an adjustable frictionband mounted on said spring and surrounding said drum, substantially as described.

4. In a sash-holder, the combination, with the drum and friction-band,of a ratchet-wheel on the axle of said drum, having teeth therein, and a wheel for engaging the sash, mounted and taking its bearing on said ratchet-wheel and having pawls for engaging the said teeth and preventingthe free rotation of the wheelin but one direction, substantially as described.-

5. In a sash holder, the combination, with the frame, the drum mounted on the spring, and the friction-baud cooperating with the said drum, of the wheel engaging the sash and the ratchet-wheel and gravitating-pawl connection between the drum and wheel, substantially as described.

6. In a sash-holder, the combination, with the main frame, the drum, and the gear-wheel mounted to one side thereof, of an adjustable friction band or brake surrounding said drum and supporting the same and mounted on a spring secured to the main frame, substantially as described.

JACOB BASTIAN.
